Features This white paper describes a tested and validated storage solution for a 7200 mailbox Exchange 2010 environment with Data Availability Group. A DAG is the new high availability mechanism in Microsoft Exchange 2010. This model of mailbox resiliency supports multiple copies of Exchange database (up to 16) in a DAG. There is only one active copy of a given Exchange 2010 database at any given time. Secondary copies are periodically synched with the primary copy. Mail clients access the primary (active) copy, and database changes to the primary copy are copied to the secondary (passive) copies in the form of transaction logs. The copied log records are played on the secondary copy to keep the secondary database copies consistent with the primary copy. The secondary hosts are configured to be identical to the primary. The primary and secondary copy storages do not share storage array controllers or disks. Dell™ PowerVault™ MD1220 is a SAS based storage enclosure. The major features of the storage system include:

Capacity for 24 2.5-inch, hot-plug, 6.0-Gbps, serial-attached SCSI (SAS) hard drives , 1TB capacity, and rated at 7.2K RPM

Support for up to 8 daisy-chained storage enclosures per channel in unified mode for a total of (192) hard drives

Host-based RAID support via a PERC H800 adapter

In-band enclosure management provided through SCSI enclosure services (SES)

RAID and system management using Dell™ OpenManage™ Server Administrator Storage Management Service

The solution presented in this paper utilizes (1) MD1220 enclosure with (24) 1TB Near-line SAS (NL-SAS) disk drives. Each disk houses one Exchange database and its transaction Logs.

Solution Description The Dell™ PowerVault™ MD1220 is a modular disk storage expansion enclosure for PowerEdge™ servers capable of housing up to (24) 2.5-inch disk drives in a single 2U rack able chassis. The expansion enclosure can support 1 Terabyte Near-Line SAS (7200 RPM) as well as 10K and 15K RPM SAS drives ranging in capacities up to 600GB. Dell™ PowerVault™ MD1220 Product Page

Figure 1:Dell™ PowerVault™ MD1220 enclosure with (24) 2.5-inch drives

PERC H800 is the host-based RAID controller used to connect to the PowerVault™ MD1220 storage enclosures. The controller supports 6 Gbps Serial Attached SCSI (SAS) as the storage interconnect technology and PCI Express 2.0 (PCI-E) as the host-based interconnect technology. The PERC H800 controller offers:

• 8 port LSI 2108 Chipset • 512MB of customized DDR2 400MHz, Error-Correcting Code (ECC) cache memory with optional upgrade to 512MB • 6 Gbps maximum speed for each SAS lane • Two external x4 (“by four”) mini-SAS wide ports, each aggregating 4 SAS lanes for a total bandwidth per port of 12.0 Gbps • x8 PCI E host interface for a total bandwidth of 32.0 Gbps • Up to 72 hours of intelligent, transportable, battery-backed, cache memory The presented solution is a Data Availability Group solution for up to 7200 mailboxes. It includes a single primary PowerEdge™ R610 server directly attached to 2 Dell™ PowerVault™ MD1200 storage enclosures. The secondary server is configured to be identical to the primary. The primary and secondary storage do not share storage array controllers or disks.

The tested user profile was 0.13 IOPS per user with a 2560 MB mailbox size. This IO profile for Exchange 2010 represents about 130 messages (sent/received) per mailbox per day. Sometimes additional applications, such as certain mobile messaging applications, can raise the IOPS profile of a user as high as three or four times that of

Storage Configuration:

The storage configuration per enclosure was as follows:

A single RAID 0 volume was created from each physical disk from 0 through 23 on the PowerVault™ MD1220 enclosure. These volumes were used for Exchange Information stores and transaction logs.

The ESRP-Storage program focuses on storage solution testing to address performance and reliability issues with storage design. However, storage is not the only factor to take into consideration when designing a scale up Exchange solution.

Other factors which affect the server scalability are:

Server processor utilization

Server physical and virtual memory limitations

Resource requirements for other applications

Directory and network service latencies

Network infrastructure limitations

Replication and recovery requirements

Client usage profiles

6

All these factors are beyond the scope for ESRP-Storage. Therefore, the number of mailboxes hosted per server as part of the tested configuration may not necessarily be viable for some customer deployment.

Best Practices Exchange Server 2007 and 2010 overcome the memory limitations of previous Exchange versions by providing support as a 64-bit application capable of running on supported x64 platforms. On Windows Server 2008 R2 x64 Edition about 2TB of addressable memory is available for the kernel mode and the user mode applications. Both the application and kernel can have sufficient memory for operations, allowing the Extensible Storage Engine (ESE) in Exchange Server 2010 to utilize more memory to buffer data pages. The result is a reduction in the number of I/Os, specifically the read operations, required to the disk sub-system. The total number of database disk I/O operations for a given user load is dependent on the available system memory. For a given load, the total database disk I/O operations required per second (IOPS) decreases over a period with increase in system memory. This decrease in database IOPS is primarily caused by a decrease in database reads. Even with the decrease in database IOPS using larger server memory, Exchange server remains a disk I/O intensive application. The disk subsystem should be capable to support both the capacity and I/O throughput demands of the application. Based on testing using the ESRP framework, we would recommend the following best practices to help improve the I/O subsystem performance:

1. Exchange 2010 is an IO intensive application. Sharing Exchange 2010 storage resources with other applications may negatively impact the performance of Exchange 2010 deployment and therefore is not recommended.

2. In our testing, the database and log folders shared the same physical disk. Other testing indicated that separating the database folders from log folders on to different set of disks does not provide a noticeable performance advantage. In an Exchange Server 2010 resiliency solution, separating the database and log folders is no longer a required best practice.

3. For Exchange 2010 Database, it is recommended that the size of elements within a RAID stripe be set 512K for best performance.

4. Windows NTFS allocation unit size for Exchange 2010 database partitions should be set to 64K for best performance. For log partitions, if separated from database, the default allocation unit size should be used.

5. Exchange Server 2010 storage latencies are most often related the number of disks available for given a workload. Windows Performance Monitor may be used to monitor Exchange Server 2010 database counters. Average database read latencies (Avg. Disk sec/Read) should not exceed 20ms.

Backup strategy

To protect e-mail data from potential disasters having a well designed and implemented backup solution is critical. Depending on the requirements of an environment different backup strategies may be implemented such as:

Backup to disk

10

Backup to tape

LAN/SAN based backup etc.

In this solution, DAG is used to maintain a passive database copy on a separate storage system. This passive copy of the database may be used to perform to tape or disk.

The tests performed for backup include: backup-to-disk (read only) and log replay. The backup-to-disk test measures the read I/O performance by running a checksum on all the databases and log files. This test can help determine what kind of database read throughput can be achieved during backups. The backup speed and throughput achieved will depend upon the backup device used. The log replay test was used to measure the maximum rate at which the log files can be played against the databases. This is used to determine the restore times and also database write throughput can be achieved during a log recovery.

Reliability

A number of tests in the framework are to check Reliability tests runs for 24 hours. The goal is to verify the storage can handle high IO load for a long period of time. Both log and database files will be analyzed for integrity after the stress test to ensure no database/log corruption. The following list provides an overview: (click on the underlined word will show the html report after the reliability tests run)

Any errors reported in the saved event log file? No errors reported on event log. No

Any errors reported in during the database and log checksum process? No

Storage Performance Results

The Primary Storage performance testing is designed to exercise the storage with maximum sustainable Exchange type of IO for 2 hours. The test is to show how long it takes for the storage to respond to an IO under load. The data below is the sum of all of the logical disk I/O’s and average of all the logical disks I/O latency in the 2 hours test duration. Each server is listed separately and the aggregate numbers across all servers is listed as well.

Database Backup/Recovery Performance

There are two tests reports in this section. The first one is to measure the sequential read rate of the database files, and the second is to measure the recovery/replay performance (playing transaction logs in to the database).

Database Read- only Performance The test is to measure the maximum rate at which databases could be backed up via VSS. The following table shows the average rate for a single database file.

MB read/sec per database 61.40 (Average)

MB read/sec total per server 1473.65

Transaction Log Recovery/Replay Performance

The test is to measure the maximum rate at which the log files can be played against the databases. The following table shows the average rate for 500 log files played in a single storage group. Each log file is 1 MB in size.

Average time to play one Log file (sec) 4.50 (avg. resp. to replay log/avg. # of logs replayed)

Conclusion This document is developed by storage solution providers, and reviewed by Microsoft Exchange Product team. The test results/data presented in this document is based on the tests introduced in the ESRP test framework. Customer should not quote the data directly for his/her pre-deployment verification. It is still necessary to go through the exercises to validate the storage design for a specific customer environment. ESRP program is not designed to be a benchmarking program; tests are not designed to getting the maximum throughput for a giving solution. Rather, it is focused on producing recommendations from vendors for Exchange application. So the data presented in this document should not be used for direct comparisons among the solutions.
